Buccal corticotomy using piezosurgery as a surgical approach for removal of deeply impacted mandibular teeth: an alternative procedure to avoid pitfalls associated with the conventional technique

Objectives: To evaluate the severity of post-operative pain after surgical extraction of impacted mandibular third molar using two different techniques i.e. comma incision and standard Wards incision. Study Design: Interventional study. Setting: Department of Oral surgery, Isra Dental College Hospital. Period: From January 2016 to June 2016. Material & Methods: A sample of 50 patients of impacted third molar was selected by non-probability purposive sampling for tooth extraction either by conventional technique or by coma shaped incision. Post-operative amount of pain was measured on 1st, 3rd and 7th day respectively. Results: Mean ± SD age in group A and B was noted as 28.5 ± 4.32 and 27.2 ± 4.39 years respectively. Male and female in groups A and B were noted as 16 (64%) and 9 (36%), & 14 (56%) and 11 (44%) respectively. Right and left lower mandibular teeth extraction in groups A and B were noted 11 and 14, & 10 and 15 respectively. Pain was measured after extraction at day 1, day 3 and day 7. Conclusion: The Coma incision was preferable over the conventional method- the standard Ward`s incision because of lesser degree of post-operative pain.

Osteoradionecrosis (ORN) is a complication of radiation therapy for which several treatment options have been reported. The use of platelet‐rich fibrin (PRF), a second-generation platelet concentrate, has been promoted in refractory wounds. A 53-year-old man underwent concurrent chemoradiotherapy for squamous cell carcinoma in the right side of the tongue. Subsequently, he exhibited pus discharge around the right maxillary first molar. Intraoral examination showed mobility and probing depths of >10 mm in teeth 15 and 16. Computed tomography revealed poorly defined osteolytic changes in teeth 15 to 17, indicative of oroantral fistula. Teeth 15 to 17 were extracted and the socket was debrided. Primary closure was achieved after PRF dressing. The wound healed within 2 weeks. The patient returned because of spontaneous loss of tooth 46 and numbness over the right lower lip. Pus was present in premolar areas and in the tooth 46 socket. Radiographic examination showed moth-eaten destruction in right mandibular teeth and better trabecular quality in the right maxilla. A provisional diagnosis of ORN was made. Debridement and primary closure after PRF dressing were performed. The mucosa healed within 3 weeks. Our findings suggest that PRF combined with a surgical approach might be useful for treatment of ORN.
